New Tactics | Main missions Wolfenstein: TNO Guide

At the beginning of the mission, Seth is going to need the welder from you. If you take a look at the table with the knives, at the top floor, it will turn out that it was taken by Fergus. He himself, is on one of the helicopters. Once you ask him about the welder, he will tell you that he accidentally dropped it into the water.

Fergus is on one of the helicopters

Now, return to the main part and find the golden door, next to the table. Cross the door, but do not jump into the water on the right. Cut out the way, using the blowtorch, in the plate next to you, and collect the welder. Of course, you cannot take the same way back.

Shoot at the chain to lower the ladder

Keep swimming ahead, until you reach the ladder. On the top, look up and shoot at the chain that suspends the ladder. Then, jump over onto the plank ahead and climb higher. This way, you will reach the big hall. On the side, there is a lever that opens the door ahead. Once you give it a pull, there will appear two Nazis in plated armors. Defeat them with the laser rifle. Remember that, if you run out of power, you can replenish it in the pods that the Nazis came out of.

The passage next to the door

After you defeat them, exit through the opened door, into the corridor. At the end, there is a locked door. Turn right, where you will find the grate of the venting shaft. After you destroy it, shoot at the chain and backtrack to the door, which is open now.

Now, keep going straight ahead, up to your base. Take the welder back to Seth and he will give you a note, which you need to deliver to Anya to complete this mission.
